Is 1490 a deficient number?

Here we will explain and calculate if 1490 is a deficient number and its deficiency if applicable.

1490 is a deficient number if the sum of its proper divisors is less than 1490.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 149 + 298 + 745 = 1210.

1210 is less than 1490. Therefore, 1490 is a deficient number.
